We present radio observations made towards the exoplanets Qatar-1b andWASP-80b near 150~MHz with the Giant Meterwave Radio Telescope. These targetsare relatively nearby irradiated giant exoplanets, a hot Jupiter and a hotSaturn, with sizes comparable to Jupiter but different masses and lowerdensities. Both the targets are expected to host extended H/He envelopes likeJupiter, with comparable or larger magnetic moments. No radio emission wasdetected from these exoplanets, with 3sigma limits of 5.9 and 5.2 mJy forQatar-1b and WASP-80b, respectively, from these targeted observations. Theseare considerably deeper limits than those available for exoplanets from widefield surveys at similar frequencies. We also present archival VLA observationsof a previously reported radio source close to Vir 61 (which has threeexoplanets). The VLA observations resolve the source, which we identify as anextragalactic radio source, i.e. a chance association with Vir 61.Additionally, we cross-match a recent exoplanet catalogue with the TIFR GMRTSky Survey ADR1 radio catalogue, but do not find any convincing associations.
